... We will have to adjust to these changes by using Table C (t-distributions) on the inside back cover of the textbook to determine critical t* values. (See p 618-19 for picture and explanation on how to use Table C) NEW PROCEDURES FOR C.I. AND SIGNIFICANCE TESTS: -We will now be doing a one sample mea ...

Dear niramol, Great questions! Here`s how I`d answer them: These
... From the normal table, we find: P(z<-2.525) = 0.00578. That's the pvalue. Hence there is very strong evidence that people in the program lose fewer than 10 pounds. ...

For GPA, the three largest values are much too large as the mean plus or minus an sd would contain all or almost of the data. The correlation coefficient r is negative, but fairly ...
